In Chapter 7 of the recently released Plan B 4.0: Mobilizing to Save Civilization, Lester Brown lays out the Plan B goals for eradicating poverty and stabilizing population. Behind the scenes are a number of datasets and graphs that delve deeper into the trends discussed in the chapter. Here are some highlights from the Chapter 7 data.
World population has grown steadily over the past half century, increasing from 2.5 billion in 1950 to a projected 6.8 billion in 2009. The United Nations medium fertility level scenario projects that world population will grow to 9.2 billion in 2050. Their high projection takes the world to 10.5 billion in 2050. Under their low projection, which assumes rapid reductions in fertility rates, population peaks at just over 8 billion in 2042, then begins to decline.
These data highlights show that while there have been some successes in the fight to reduce poverty and improve quality of life around the world, many challenges remain, particularly in the face of continuing population growth.
